BEST MODE FOR CARRYING OUT THE INVENTION A portable information device according to the present invention will be described in detail below with reference to preferred embodiments and with reference to the accompanying drawings.

FIG. 1 is a perspective view of a portable information device 10 according to one embodiment. As shown in FIG. 1, the portable information device 10 includes a main housing 12, a display housing 14, and a hinge device 16. As shown in FIG. The portable information device 10 of the present embodiment is a clamshell notebook PC in which a main housing 12 and a display housing 14 are relatively rotatably connected by a hinge device 16 . INDUSTRIAL APPLICABILITY The present invention can be applied to various information devices other than notebook PCs, such as tablet PCs, mobile phones, smart phones, portable game machines, and electronic notebooks.

Hereinafter, the main housing 12 and each element mounted therein will be described with reference to the direction viewed from the user using the portable information device 10 shown in FIG.

First, the overall configuration of the portable information device 10 will be described.

As shown in FIG. 1, the main housing 12 is a flat box-shaped housing. A keyboard 18 and a touch pad 19 are provided on the upper surface of the main body housing 12 . Inside the body housing 12, in addition to a board 20, a CPU 21 and a battery device 22 (see FIG. 2), various electronic components such as a hard disk device and memory (not shown) are accommodated. A pair of left and right antenna elements 24 are provided at the front edge portion inside the main housing 12 .

The display housing 14 is a flat box-shaped housing that is thinner than the main body housing 12 . A display 26 is provided on the front surface of the display housing 14 . The display 26 is, for example, a liquid crystal display. A pair of left and right antenna elements 28 are provided in the upper bezel of the display 26 in the display housing 14 .

The hinge device 16 connects between the rear edge of the main housing 12 and the lower edge of the display housing 14 . A pair of left and right hinge devices 16 are provided, for example.

Next, a specific configuration example of the internal structure of the main housing 12 will be described. FIG. 2 is a bottom view schematically showing the internal structure of the main housing 12. As shown in FIG. FIG. 3 is an enlarged schematic perspective view of the module mounting portion 34 and its peripheral portion shown in FIG.

As shown in FIGS. 2 and 3, the main housing 12 accommodates a substrate 20, a CPU 21, a battery device 22, a cooling device 30, a plurality of external connectors 31, an antenna module 32A (or 32B), a module mounting portion 34, and left and right antenna elements 24. Reference numeral 35 in FIG. 2 denotes a notch-shaped concave portion in which the hinge device 16 is arranged, and is formed at the rear end portion of the main housing 12 .

The board 20 is the motherboard of the portable information device 10 . The substrate 20 has a size that occupies substantially the rear half of the area inside the main housing 12, for example. A CPU 21 is a central processing unit mounted on the board 20 . In addition to the CPU 21, various semiconductor chips such as a graphic chip are mounted on the substrate 20, and various memories are connected.

The cooling device 30 has a cooling fan 30a and a heat pipe 30b. The cooling fan 30 a is arranged, for example, facing an air outlet 36 formed in the rear end surface of the main body housing 12 and blows air out of the main body housing 12 through the air outlet 36 . One end of the heat pipe 30b contacts the CPU 21 via a predetermined metal plate, and the other end is interposed in the air outlet of the cooling fan 30a. The heat pipe 30b efficiently transports the heat of the CPU 21 to the cooling fan 30a. Since the cooling fan 30a faces the exhaust port 36, the substrate 20 is formed with an arcuate cutout 20a for avoiding the cooling fan 30a at the rear edge where the cooling fan 30a is arranged. That is, the substrate 20 has a narrow portion 20b formed by the notch portion 20a in the front portion located slightly to the right of the central portion in the left-right direction.

The external connector 31 is mounted on the substrate 20 and opens to the outer surface of the main housing 12 . The external connector 31 is, for example, a connector conforming to the USB standard or the like, or a connector conforming to a communication standard such as video. In this embodiment, the external connectors 31 are arranged facing the right side surface of the main body housing 12, and are arranged in a line of three in the front-rear direction at a rearward position on the right side surface. The external connectors 31 arranged in front and behind are stably held on the surface of the board 20 by one bracket 37 . The bracket 37 is a strip-shaped metal plate extending in the front-rear direction, and both front and rear ends thereof are screwed to the substrate 20 . Small-diameter protrusions 37A and 37B are arranged in the front-rear direction on the rear end side of the bracket 37 so as to protrude therefrom.

The antenna module 32A (hereinafter also simply referred to as "module 32A") is a processing device compatible with, for example, the communication standard of the fourth generation mobile communication system (4G). The antenna module 32B (hereinafter also simply referred to as "module 32B") is a processing device compatible with, for example, the fifth generation mobile communication system (5G). Either one of the modules 32A and 32B is selectively installed in the portable information device 10 of the present embodiment according to the required specifications.

The module 32A is connected to two antenna elements 28 mounted on the display housing 14 via antenna wires 28a. The module 32A is a communication module capable of wirelessly communicating with an external base station or the like via the antenna element 28 . The antenna wire 28 a is routed from the main housing 12 to the display housing 14 through the hinge device 16 .

The module 32B is connected to two antenna elements 28 mounted on the display housing 14 via antenna wires 28a, and is also connected to two antenna elements 24 mounted on the main housing 12 via antenna wires 24a. The module 32B is a communication module capable of wirelessly communicating with an external base station or the like via the antenna elements 24,28.

FIG. 4A is a schematic bottom view of the antenna module 32A. FIG. 4B is a schematic bottom view of the antenna module 32B.

As shown in FIG. 4A, the module 32A is configured in a thin box shape, and connection terminals 38 protrude from the front end surface. The module 32A has a terminal portion 39a to which the antenna wire 28a is connected on the surface on the rear end side. The terminal portion 39a is, for example, a pin to which the tip connecting portion of the antenna wire 28a is fitted, and is formed on a thin board portion formed on the rear edge portion of the module 32A. A mounting portion 40 cut out in a semicircular shape is provided at the center of the rear end portion of this substrate portion.

As shown in FIG. 4B, the module 32B is configured in a thin box shape, and connection terminals 38 protrude from the front end surface. The module 32B has a terminal portion 39a to which the antenna wire 28a is connected and a terminal portion 39b to which the antenna wire 24a is connected on the surface on the rear end side. The terminal portion 39b has a structure similar to that of the terminal portion 39a, and is, for example, a pin to which the tip connecting portion of the antenna wire 24a is fitted. The mounting portion 40 is also provided at the center of the thin board portion formed at the rear end portion of the module 32B.

As shown in FIGS. 4A and 4B, the distance LA from the connection terminal 38 of the module 32A to the mounting portion 40 is shorter than the distance LB from the connection terminal 38 to the mounting portion 40 of the module 32B. The difference between the distances LA and LB is due to, for example, the number and size of processing chips mounted on the respective modules 32A and 32B, the difference in communication standards, and the like. Therefore, the module mounting portion 34 is configured to easily cope with the difference in the distances LA and LB between the modules 32A and 32B.

As shown in FIGS. 2 and 3 , the module mounting portion 34 has a connector 42 , a pair of front and rear fastening portions 44 A and 44 B, an opening 46 , and a cut line 48 . The module mounting portion 34 of this embodiment is arranged near the right rear corner of the board 20 , that is, near the external connector 31 .

The connector 42 is mounted on the surface of the substrate 20, and the connection port faces rearward. The connector 42 is connected to one of the connection terminals 38 of the modules 32A and 32B. The connector 42 is formed on the substrate 20 and connected to the CPU 21 using a wiring 42a passing through the narrow portion 20b. In the portable information device 10, the notch 20a is formed in the substrate 20 due to the cooling fan 30a, and it is difficult to route the wiring 42a along the rear end portion of the substrate 20. FIG. Therefore, the connector 42 is installed on the front side of the fastening portions 44A and 44B, that is, at a position close to the narrow portion 20b, thereby enabling smooth routing of the wiring 42a. At the same time, by adopting this configuration, the later-described terminal portions 39a of the modules 32A and 32B are arranged at positions close to the hinge device 16 through which the antenna wire 28a from the antenna element 28 is passed.

The fastening portion 44A is used when attaching the 4G module 32A. The fastening portion 44A is arranged behind the connector 42 with the opening 46 interposed therebetween. The fastening portion 44B is used when attaching the 5G module 32B. The fastening portion 44B is arranged behind the fastening portion 44A. The fastening portions 44A and 44B are holes formed in the substrate 20, for example. The distance between the fastening portion 44A and the connector 42 is the distance LA (see FIG. 4A). The distance between the fastening portion 44B and the connector 42 is the distance LB (see FIG. 4B).

In this embodiment, when the modules 32A and 32B are attached, a boss member 50 is fixed to one of the fastening portions 44A and 44B, and a female screw hole formed in the boss member 50 is fastened with a screw 52 (see FIGS. 5C and 6C). The boss member 50 may be fixed in advance to each of the fastening portions 44A and 44B. However, in this embodiment, since the boss members 50 are fixed only to the fastening portions 44A and 44B used as described above, the weight of the substrate 20 is reduced.

The opening 46 is formed by hollowing out a portion of the substrate 20 in a substantially rectangular shape. The opening 46 is formed between the connector 42 and the fastening portion 44A. The lateral width of the opening 46 is slightly smaller than the width of the modules 32A, 32B (see FIGS. 5B and 6B). The opening 46 is located at a dead space of the substrate 20 where other electronic components cannot be mounted because it is covered with the modules 32A and 32B, and contributes to the weight reduction of the substrate 20. FIG. The opening 46 may be omitted.

The perforation line 48 is a perforated cut-out hole formed in the substrate 20 so as to surround the fastening portion 44A, and extends, for example, in a substantially rectangular shape. The perforation line 48 of this embodiment is formed by perforation-like broken lines in which one side of the front side is shared by the opening 46 and the other three sides are arranged with narrow holes. The perforated line 48 may be shared by the opening 46 or another opening on the sides other than the front side. If the opening 46 is omitted, the perforation line 48 may be formed by extending a perforated broken line in the shape of a rectangular frame. Substrate 20 can easily be cut at its inner portion (cut-out area 48 a ) along tear line 48 . The cutout area 48a is left when the module 32A is mounted, and is cut off when the module 32B is mounted.

Next, one procedure of a method of mounting the modules 32A and 32B to the module mounting portion 34 will be described in order.

First, a method for attaching the 4G module 32A will be described. 5A to 5C are explanatory diagrams of a method of attaching the module 32A to the module attachment portion 34. FIG. 5A to 5C are enlarged views of the module mounting portion 34 and its peripheral portion in FIG.

As shown in FIG. 5A, when attaching the module 32A, first, the boss member 50 is fixed to the fastening portion 44A closer to the connector 42. As shown in FIG. The boss member 50 is joined to the substrate 20 by soldering or the like while being fitted to the fastening portion 44A. Since module 32A is attached using fasteners 44A, cutout area 48a is left uncut.

Subsequently, as shown in FIG. 5B, the connection terminals 38 are inserted into the connector 42 from the rear to the front for connection, and the module 32A is placed on the substrate 20 with the attachment portion 40 aligned with the boss member 50 . Before or after this work, the antenna wire 28a from the antenna element 28 is connected to the terminal portion 39a of the module 32A. However, in the state shown in FIG. 5B, the antenna wire 28a is in a state in which the pin-shaped terminal portion 39a is only fitted with the tip portion, and there is a concern that the antenna wire 28a may fall off the terminal portion 39a.

Therefore, as shown in FIG. 5C, a retainer plate 54 is attached from above the thin plate portion of the trailing edge of the module 32A. The holding plate 54 is a strip-shaped metal plate extending in the left-right direction. The holding plate 54 is a member that holds down the antenna wire 28a and prevents it from coming off the terminal portion 39a. The holding plate 54 has a through hole 54a near the left end and a hole 54b having a smaller diameter than the through hole 54a near the right end. The screw 52 can be inserted through the through hole 54a. The projection 37A (37B) of the bracket 37 can be inserted into the hole 54b.

The projection 37A of the bracket 37 is positioned so that it can be fitted into the hole 54b of the bracket 37 when the module 32A is mounted. Moreover, the projection 37B is located at a position where it can be fitted into the hole 54b of the bracket 37 when the module 32B is mounted. That is, when mounting the module 32A, the holding plate 54 is reliably positioned by fitting the hole 54b into the projection 37A. The retaining plate 54 may be omitted.

Finally, as shown in FIG. 5C, the screw 52 is fixed to the female threaded hole of the boss member 50 through the through hole 54a of the retaining plate 54. As shown in FIG. As a result, the retaining plate 54 and the module 32A are fastened together to the substrate 20 by the screws 52, and the antenna wire 28a is clamped between the retaining plate 54 and the module 32A to prevent it from coming off. This completes the attachment of the module 32A. In the holding plate 54, the hole 54b at the end opposite to the through hole 54a is fitted with the protrusion 37A, so that the screw 52 is prevented from rotating during tightening.

Next, a method for attaching the 5G module 32B will be described. 6A to 6C are explanatory diagrams of a method of attaching the module 32B to the module attachment portion 34. FIG. 6A to 6C are enlarged views of the module mounting portion 34 and its peripheral portion in FIG.

As shown in FIG. 6A, when attaching the module 32B, first, the cutout region 48a formed with the unnecessary fastening portion 44A is cut off from the substrate 20 along the cutout line 48. As shown in FIG. As a result, the opening 46 has a shape enlarged to the rear end of the perforation line 48 as shown in FIG. 6A. Then, the boss member 50 is fixed to the remaining fastening portion 44B. The fixing method of the boss member 50 to the fastening portion 44B may be the same as the fixing method to the fastening portion 44A described above.

Subsequently, as shown in FIG. 6B, the connection terminals 38 are inserted into the connector 42 from the rear to the front for connection, and the module 32B is placed on the substrate 20 with the mounting portion 40 aligned with the boss member 50 . Before or after this work, the antenna wire 28a from the antenna element 28 is connected to the terminal portion 39a of the module 32B, and the antenna wire 24a from the antenna element 24 is connected to the terminal portion 39b.

Then, as shown in FIG. 6C, a retaining plate 54 is pressed from above the thin plate portion of the trailing edge of the module 32B. When mounting the module 32B, the holding plate 54 is positioned by inserting the hole 54b into the protrusion 37B of the bracket 37. As shown in FIG.

Finally, as shown in FIG. 6C, the screw 52 is fixed to the female threaded hole of the boss member 50 through the through hole 54a of the retaining plate 54. As shown in FIG. As a result, the retaining plate 54 and the module 32B are fastened together to the substrate 20 by the screws 52, and the antenna wires 24a and 28a are clamped between the retaining plate 54 and the module 32B to prevent them from coming off. This completes the attachment of the module 32B. Also in this case, the retaining plate 54 is prevented from rotating when the screw 52 is tightened because the hole 54b is fitted with the protrusion 37B. A configuration in which the holding plate 54 is provided with the protrusions 37A and 37B and the bracket 37 is provided with the hole 54b may be employed.

As described above, in the portable information device 10 of the present embodiment, the board 20 has the fastening portions 44A and 44B that are different in distance from the connector 42 . If there are three or more types of antenna modules to be attached to the portable information device 10, the number of fastening portions may be increased as necessary. The modules 32A and 32B are fixed to the substrate 20 by connecting the connection terminals 38 to the connector 42 and selectively fastening the screws 52 to one of the fastening portions 44A and 44B via the attachment portion 40 .

Therefore, in the portable information device 10, one of the plurality of types of antenna modules 32A and 32B having different shapes can be selectively attached to the substrate 20 using one of the fastening portions 44A and 44B for reasons such as different communication standards or different manufacturers. In other words, the portable information device 10 can flexibly accommodate the modules 32A and 32B simply by forming the fastening portions 44A and 44B with different distances from the connector 42. FIG. As a result, the portable information device 10 does not need to change the structure of the substrate 20 or the like depending on the type of antenna module, and can support multiple specifications at low cost.

Moreover, in the portable information device 10 of the present embodiment, the circuit board 20 is provided with a perforation line 48 formed so as to surround the fastening portion 44A located closest to the connector 42 . Then, when mounting the module 32B using the fastening portion 44B instead of the fastening portion 44A, the substrate 20 can be easily cut off at the cutout area 48a surrounded by the cutout line 48. FIG. As a result, the portable information device 10 can easily remove the dead space (the cutout area 48a) of the substrate 20 covered with the module 32B when unnecessary, and the weight of the cutout area 48a can be reduced.

Thus, cutout area 48a is cut away during installation of module 32B. Therefore, as shown in FIG. 7, the wiring 56 is passed through the substrate 20 at a position avoiding the cutout region 48a. In other words, the cutout area 48a that is cut according to the selection of the modules 32A, 32B has no wiring and, of course, no mounting of electronic components. Therefore, when manufacturing the portable information device 10, the cutout region 48a can be removed as necessary without considering the disconnection of the wiring 56, and the influence thereof does not occur. In other words, when the antenna module 32A is attached to the substrate 20 using the fastening portion 44A and the cutout region 48a is not cut out and used, wiring that electrically conducts the inside and outside of the cutout region 48a is not formed therein. The wiring 56 is wiring from the external connector 31 to the CPU 21, for example.

As shown in FIG. 8, the substrate 20 may be configured with a separate tear line 58 along with the tear line 48 . The perforation line 58 has substantially the same shape as the perforation line 48, is provided behind the perforation line 48, and surrounds the rear fastening portion 44B. The perforation line 58 is formed by, for example, a perforation-like broken line in which narrow holes are arranged on the other three sides, while one side on the front side is also used as the perforation line 48 . Therefore, by providing the cutoff line 58 in the substrate 20, when a specification in which no modules 32A and 32B are mounted is selected, the cutout area 48a and the inner cutout area 58a along the cutoff line 58 can be easily cut off, further reducing the weight. In the configuration having the perforation line 58, the wiring 56 and the like must avoid not only the perforation area 48a but also the perforation area 58a.

FIG. 9 is an enlarged perspective view of a main part schematically showing a state in which the module 32A (32B) is connected to the connector 60 according to the modification.

As shown in FIG. 9, the connector 60 is attached to the end surface 20c of the substrate 20 formed by the opening 46 and faces the opening 46. As shown in FIG. In this configuration, the opening 46 has a shape that allows insertion of most of the module 32A (32B) except for the terminal portions 39a and 39b and the thin plate portion at the rear end where the mounting portion 40 is formed. Thereby, the module 32A (32B) is accommodated in the opening 46 when the connection terminal 38 is connected to the connector 60. As shown in FIG. As a result, the module 32A (32B) protrudes from the surface of the substrate 20 by a smaller amount than in the above configuration using the connector 42, which contributes to making the body housing 12 thinner.

It goes without saying that the present invention is not limited to the above-described embodiments, and can be freely modified without departing from the gist of the present invention.
